What is the si unit for acceleration?

The SI unit for acceleration is meters per second squared (m/s^2). Acceleration is a vector quantity, meaning it has both magnitude and direction. It is defined as the rate of change of velocity over time, calculated by dividing the change in velocity by the time taken for the change to occur.

Acceleration can be positive, negative, or zero, depending on whether the object is speeding up, slowing down, or maintaining a constant velocity. It is commonly measured in meters per second squared, as it represents the change in velocity in meters per second over a one-second period.

Acceleration plays a crucial role in physics, as it is a fundamental concept in understanding motion and the forces acting on objects. It is a key component in Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
